Para Generation and Drawing Conclusion from X give Articles
Paraphrase generation would be made by an abstractive text summarization tool like Tensorflow as described in Google's blog. 

Abstractive tool summarizes the text but also it adds extra words to make text more human like.

About the second problem scenario I would say the answer depends quite much what you mean by the conclusions and how you think the conclusions would be made. I strongly believe this falls in the category of artificial general intelligence, which is emerging area of AI, supported by association AGI, where the focus is on strong artificial intelligence and more human like features of AI. 

Judging about conclusions at least needs a vast knowledge base of the semantics of different words and pieces of text in general combined to possible conclusions and their legitimate implications.
